Set up your own cameras and publish publicly the movements of politicians that claim this is for safety. Nothing illegal about pointing a camera at the entrance to city hall and logging entries and exits of politicians to a website. Hell, afaict, nothing illegal about pointing a camera at their house and doing the same.
Something in the spirit of celebrity jet trackers, but at a local level.
The hardware/software isn't particularly difficult. Some loudmouth like Rossman could get this moving.
Nothing to hide, nothing to fear right?
There's a very small number of people committing crimes worthy of these cameras, and there's also a small number of people not willing to do business with clients of camera purveyors.
